the trio colored diamond engagment ring | solid gold
Tax included. Shipping calculated at checkout
Our trio engagement ring is now available with a wonderful, lab-grown colored diamond. Choose between a soft pink, vibrant yellow, or radiant blue. Alongside two white lab-grown diamonds, the colored diamond serves as the highlight of this ring. Minimalist yet unique—who could say no to that?
Production time for this unique engagement ring is 4–6 weeks.
The ring is made to your desired size; please enter the correct ring size in the 'Desired Size' field. The ring can be crafted in 14k yellow gold, rose gold, or sleek white gold. You can find helpful tips on determining the right ring size on our blog post on measuring ring sizes, along with a matching ring size chart available for download.
We ship the ring in a high-quality, eco-friendly case—made for the perfect proposal!
Size Adjustments: The ring should ideally be purchased slightly larger rather than too small; later on, a stacking ring or wedding band can secure the fit. Subsequent, fee-based size adjustments should be avoided if possible due to the set diamonds: the engagement ring can only be resized by a maximum of one size up or down (e.g., from 52 to 53 / 16.5 mm inner diameter to 16.9 mm and vice versa).
Returns: Should you need to return your custom-made engagement ring, we can unfortunately only refund 50% of the purchase price. In the event of an incorrect delivery on our part, we will of course refund 100% of the purchase price. Thank you for your understanding!

Don't know your ring size? Here we have a few tips on how you can easily determine your size.
Upon request, we can also increase or decrease your favorite ring by 1-2 sizes.
Your piece of jewelry is made of solid 14K gold and is designed to last a lifetime. Since it is not gold-plated, the gold layer cannot wear off.
Even real gold can develop fine scratches and signs of wear over time from daily wear. Cosmetics, perfume, chlorine, or other external factors can also affect the surface. We therefore recommend handling it with care and cleaning it regularly and gently, for example, with a soft cloth or a mild cleaning solution.
Is your piece of jewelry defective, or did something break while you were wearing it? Feel free to contact us. We’ll check whether it’s covered under warranty or what options our repair service offers.
